## Competency 15 Patterns and Algebra

 True
 True or False? Only like algebraic terms (same exponent) can be added or subtracted to produce a simple expression Ex: 2x3 and 3x3 = 5x3
 True
 True or False? Multiply the constant term and add the exponents. Ex: 4w2 x 8w3 = 32w5
 True
 True or False? When dividing algebraic terms, always subtract the exponents. Ex: 2x7 / 5x3 = 2x 7-3 = 2x4/5
 Non-Linear Function
 Function graphed as an unstraight line
 Linear Functions
 Functions graphed as a straight line
 Expressions
 Group like terms together when solving these   Ex: 3x+4-2x+1 = 3x-2x + 4+1 x=5
 Ordered Pairs
 When graphing these, move horizontally 1st then move up or down vertically to the 2nd number
 Equations
 When solving these, perform the invrse operation to get the vaiable by itself.   Example: t-5 = 27 t-5+5 = 27+5 t = 32
 Y-Axis
 The line that goes up and down, the vertical line is the
 X-Axis
 The line that goes left to right, the horizontal line is called the…
 Patterns
 Helps with: making predictions finding connections looking for similarities and differences
